My car was going in to limp mode for no reason the computer found the egr valve was the problem so it was replaced to find out it still happens put it back on the computer it was the break switch under passenger side we replaced it and it has fixed it so do look at that before you pay out loads of money

Never heard of a brake switch on any car causing that before or affecting the turbo .
